My invention relates to a humidifier and air washer that is particularlyadapted for use in homes, oflices, theaters, railroad coaches, etc. inorder that the air may be kept up to a desirable humidity.

Referring to the drawings for a more complete disclosure of theinvention:

Fig. 1 is a vertical section of the humidifier;

Fig. 2 is a section on the line 2-2 of Fig. 1; and

Fig. 3 is a section on the line 33 of Fig. 2.

The device comprises a casingl that is provided with a plurality oflouvers 2 in its upper portion. On the upper end of the casing a cover 3is secured by screws 4. Depending from the cover 3 is an air tube 5.-Over the air tube an electric motor 6 is supported on a removable base7, which merely sets on pins with a rubber cushion underneath andbetween the motor base 7 and casing 3, which is provided with apertures8 through which air,from the surrounding atmosphere, may enter the airtube 5. A cord 9 connects the motor with an electric light socket.Depending from the motor is a. power shaft 10 and keyed on the powershaft is a fan 11.

Supported in the casing 1 is a stationary conical disc 12, secured inadjusted rotatable position by the bolts 13, and provided with a column14 in which there is a well 15. The lower end of the column 14 isprovided with a flange which is supported on the flange 18 on the bottomof the casing.

Supported on the disc 12 are a circle of fiat baflles 19 and arrangedwith their widest flat faces along the radius of the circle. Surroundingthe fiat battles are round baffles 20. The upper edge of the well isprovided with a curved edge 21 which acts as a mist guide.

Mounted to rotate in the well is a funnel disc 22, which has secured toits upper end raised corrugations 23 which act as fan blades to throwthe water at an angle of about 45 degrees against the fiat faces of thebafiles 19 and also to circulate the mist laden air.

Slidably keyed'on the power shaft 10 is a water breaker cone disc 24,rovided with notches on its edge, throug which water passes on its wayto the corrugated fan blades '23, the size of the notches regulating theamount of water that passes through them. The disc 24 is held in placeby a compression spring 25 interposed between it and a washer 26 held bya pin through the shaft 10, which also holds the funnel disc in place onthe bearing at its lower end. The disc 24 also slerves to center thepower shaft in the funnel At the base of the funnel disc 22 is a wateropening 27 which is used on machines of the larger type where the funneldisc 22 rests on the ball bearing 29, which closes the opening in thebottom of the funnel disc. In the smaller type of machines, where thefunnel disc 22 is not supported by the ball bearing 29, but swingsindependently of the same, the water opening 27 is not necessary becausethe water can enter at the bottom of the funnel disc.

For supporting the lower end of the funnel disc, there is provided abearing 28, sup- Eorted'on a ball bearing 29, carried by a ball earingspring 30 which rests on a felt bearing 31 in the bearing lug 35. Thebearing lug is below the base of the reservoir 17 so that when thereservoir is empty, there is enough water in the bearing lug forlubricating the ball bearing and funnel disc bearing.

Apertures 32 in the disc 12 return the precipitated mist to the waterchamber 17.

Around the wall of the well, I place a plurality of fins 33, so arrangedas to stop the whirl of the water so that the funnel disc can pick itup. If the fins were absent, the water would whirl in the same directionas the funnel disc and the water would not be picked up by the funneldisc.

At the bottom of the well, is a water intake 34 consisting of holes atthe bottom of the Well and provided with a screen 16 to prevent thepassage of dirt from the water chamber 17 into the well. To regulate theamount of water entering the well, the screws 9 13 are loosened, and thestationary cone 12 turned to the right to open the openings 34 and tothe left to close them.

The machine is provided with legs 36 having felt pads 37 on theirbottoms so that it can be on a table or wherever desired when inoperation.

By removing the screws 4 and cover 3, the funnel disc 22 and stationscone 12 can be removed for cleaning. en in use, the machine should becleaned every ten days or two weeks, because the dirt that is washed outof the air settles in the bottom of the water chamber 17. By removingthe motor base 7, the funnel base can be removed without removin themain cover.

In operation, the funnel disc revolves at 950-1750 R. P. M. Water willenter the o in the lower portion of the funnel disc and be forced upthrough it to the corru ted fan or water breaker 23. Here it is orcedout against the ed e bafiles 19 and the round baflles 20 attache to thestationary disc 12. By this tremendous force the water is broken u intoa fine mist. The action of the air tom the fans 11 and 23 drives thismist upward and out through the mist and air louvers 2. The fan 11 keepsup a circulation of air drawing it in throu the air openings 8, w ere itenters the air tu e 5. It is then forced down through the mist where itis washed. It is then carried to the top of the humidifier where itescapes through the louvers 2.

What I claim as new and useful and desire to secure by Letters Patent ofthe United States is:

1. In a humidifier, a casing, means within the casing to convert waterinto mist, comrisin a well adapted to contaln water, a nne in the well,means for rotating the funnel to raise the water, a water breakercarried by the funnel and stationary flat baffles adjacent the funneland adapted to further break up the water received from the waterbreaker, and round baflles surroundthe flat baflles. In a humidifier, acasing, means within the casing to convert water into mist comprising areceptacle adapted to contain water, a well in the receptacle, a funnel1n the well, means for rotating the funnel to raise the water,comprising a power shaft a water breaker cone disc in the funnel and onthe 5. In a humidifier, a casing, means within the casing to convertwater into mist and comprising a stationary inverted truncated coneconnected to the walls of the casing, a well thereunder, a rotary funnelin the well and stationary baflies carried by the said cone.
